The soil-moisture monitoring network used in this study is compromised of 6 profilers (each covering a depth of 2 m) with 4-5 sensors per profile, located at different depths.

My soil-moisture reading was in the low 700s in soil that had around 30 percent moisture (according to a comparison with a commercial soil-moisture sensor), and 661 in a drier pot.

The SparkFun Soil Moisture Sensor measures the moisture level in the soil, ensuring that the plant receives the right amount of water.
